How to Get a Yahoo! Messenger ID
Yahoo Messenger uses the same ID as your Yahoo Email. If you already have Yahoo Email, you can just log in to Yahoo Messenger with that. If this is your first time signing up for Yahoo services, you must register for an account through the Yahoo website. The account gives you access to Yahoo Messenger for instant messaging, Chat for group chats (accessed through Yahoo Messenger), and Games and Email that can be accessed through the Yahoo website. You are getting a lot more than just instant messaging by having a Yahoo ID.
